Medium capacity and medium-high pressure centrifugal fans with a backward curved impeller PN-L ≤32400 m³/h

• the PN-L series of centrifugal fans are designed to transport clean or lightly dusty air up to +60 °C. They are suitable for all industrial applications where medium air volumes and medium-high pressures are required. The series consists of different models with impeller diameters from 400 to 630 mm. The backward curved impeller offers extremely high aerodynamic efficiency. The casing is easily adjustable to the required discharge angle in 45° increments, including 180° and 225° positions
• other modifications of the PR-L series:

1. PN-L INOX - centrifugal fans with stainless steel casing for the transport of corrosive gases or fumes up to +60 °C.
2. PN-L AT - centrifugal fans for the transport of clean or lightly dusty air and smoke up to +150-300 °C
3. PN-L ATEX - explosion-proof centrifugal fans for the transport of clean air or smoke up to +40 °C

• housing positions (price may vary when ordering with RD housing)::
